As the saying goes.. 'Amateur's talk strategy. Professionals talk logistics"
I heard numerous reports from early on about all manner of shortages of necessary materials and labor in this pandemic. There is simply not the manufacturing capacity on the planet to make alot of this stuff - esp. atthe speed and quantity to outpace the virus mutations. Many vax trials I follow are being held up by insane supply problems. When you add on the fact that it appears many of them need boosters.. I suspect this will remain a largely first world technology.
Sadly even solving this would not drive covid out.. it has animal hosts as well. We will be in a permanent fight with this one.
